AUTOMATIC FLOW-CONTROLLER.

Specification of Letters Patent.

rammed Feb. 18, 190s.

Application filed July 11- 1907- Serialllo. 383.189.

' when itis desired to maintain a predetermined rate of flow regardless of the variations in head.

The leading object is to provide a simple, inexpensive and eflicient mechanism controlled by variations in the head to control the flow.

In the accompanying drawings, Figure 1 is a sectional elevation representing a form of the invention, and Fig. 2 is a sectional elevation representing a second form thereof.

As shown in the drawings, the filter 1* discharges water by the conduit 2 into the etfiuent chamber 3, the conduit having the restrictedoutlet or nozzle 2. In the conduit is journaled the balanced valve 4 to which is fixed a lever 5 having the adjustable poise 6 thereon. The lever 5 is connected by a coupling as a chain 7 with an arm of a lever 8, which is balanced on the standard 9.v

As shown in Fig. 1, the balanced lever 8 has an arm, connected by the coupling 10 with a vessel 11, which tends to close the valve. A tube 12, controlled by a valve 13, provides a restricted passage connecting the conduit 2, at a point in the rear of its outlet,

with the vessel 11, the outlet end of the tube passing through a nipple 1 1 which'rises from the bottom of the vessel and moves freely on the tube section passing therethrough. The tube is provided with a lip 12 for directing liquid into the vessel and the vessel is provided with the bottom orifices 11".

A portion of the water flowing in the conduit passes through the tube into the vessel from which it flows continuously through the bottom orifices into the effluent chamber. The amount of water or variable load in the thereof connecte vessel 15 ha'vin vessel will depend upon the head or pressure inducing flow throu h the tube and will regulate the position of 516 valve, the latter being fully open with the minimum head and gradually closing as the pressure or head rises so that the water accumulates in the vessel.

As shown in Fi 2, the lever 8 has an arm by a coupling 14 with a orifices 15 in its bottom. The nozzle 2' ischarges the whole'of the water through the spout or restricted passage 2 into the vessel, the water flowing thence through the orifices 15 into the efiluent chamber. With the minimum pressure or head the valve is fully open and as the flow increases so as to lower the vessel the valve is closed proportionately.

Having described my invention, I claim:-

1. The combination of a conduit, a valve for controlling said conduit,'a vessel into which said conduit discharges, and mechanism whereby the load in said vessel regulates said valve so as to maintain a substantially uniform rate of flow through said conduit.

2. The combination of a valve, a vessel having a restricted outlet for continuously discharging a liquid delivered thereto, and mechanism whereby the load in said vessel regulates the position of said valve.

3. The combination of a conduit, a balanced vessel having an outlet through which its variable load discharges continuously and automatically, and means whereby the position of said vessel controls the flow through said conduit.

4. The combination of a conduit, a valve in said conduit, a fulcrumed lever connected with said valve, and a vessel connected with said vessel having a constantly open outlet and said lever, said conduit discharging into said vessel.

5. The combination of a filter, an efliuent chamber, a conduit connecting said filter with said chamber, a valve controlling said conduit, a vessel, and balancing mechanism connecting said valve and vessel whereby the load in sa1d vessel regulates said valve.

6. The combination of a filter, with a conduit having a contracted passage connected therewith, an effluent chamber to which said my name this 6th day 155 July, 1907, in the coniduit (ilischarges, s11. valfi e for controlling presence of the subscrib' gwitnesses. sai con uit, a vesse wit one or more ischarge openings into which said contracted JOHN LEDOUX' 5 passage discharges, and balancing mechan- Witnesses: ism connecting said valve and Vessel.
